Sandpaper Selection

Selecting the correct grit of sandpaper is an important step in achieving optimum
results. Coarse grit will remove the most material. Finer grit will produce a smoother
finish. The condition of the workpiece will determine the grit of the sandpaper to be
used. The higher the grit number, the finer the grade of sandpaper.

If the surface is rough, start with a coarse grit and sand until the surface is uniform.
Medium grit may then be used to remove scratches left by the coarser grit. Finer grit is
then used to finish the surface. Always continue sanding with each grade of sandpaper
until the surface is uniform.

Note:

If intermediate sanding is required, choose a grit rating between coarse and

fine. The above table is intended as a guide only. To ensure a satisfactory result, a
small, inconspicuous area should first be tested to ensure the grit of sandpaper chosen
is suitable for the desired finish.

Precautions to Take When Sanding Paint

CAUTION: A dust mask should be worn at all times

Any finish, such as paint or resin, may soften from frictional heat. This will cause the
material to rapidly clog the sandpaper, rendering it useless. A heat gun will remove
paint more effectively before sanding. 

CAUTION: Follow all safety instructions in the heat gun's instruction manual.

Environmental Safety

•

Paint should be removed in a manner which minimises the amount of dust generated.

•

Areas where paint removal is occurring should be sealed with plastic sheeting.

•

Sanding should be done in a manner which reduces the tracking of paint dust
outside the work area.

Cleaning and Disposal

•

All surfaces of the work area should be vacuumed and thoroughly cleaned daily for
the duration of the sanding project. Vacuum filter bags should be changed frequently.

•

Plastic drop sheets should be gathered up and disposed of along with any dust
chips or other debris. They should be placed in sealed refuse receptacles and
disposed of through regular garbage pick-up.

•

During clean-up, children and pregnant women should be kept away from the
immediate work area.

•

All toys, washable furniture and utensils used by children should be washed
thoroughly before use.
